The Shoshonis: Sentinels of the Rockies is a comprehensive historical study of the Shoshone people, focusing on their cultural development, social organization, and interactions with Euro-American explorers, settlers, and the U.S. government. Placing the Shoshone within the broader context of the American West, Trenholm and Carley trace the tribe’s origins in the Great Basin and their eventual movement into the Rocky Mountains and Plains. The narrative foregrounds key figures such as Chief Washakie and explores how the Shoshone exercised political agency and navigated shifting power dynamics during the nineteenth century. Rather than emphasizing warfare alone, the work analyzes the profound cultural changes wrought by contact and conflict with white settlers and the U.S. state, documenting how the Shoshone served as literal and symbolic ‘sentinels’ of the Rockies. Richly illustrated and supplemented with maps, notes, and a substantial bibliography, this volume has been considered a standard reference on Shoshone history and Indigenous-settler relations in the American West.
